Description
Technical field
The present invention relates to vegetable oil processing technique fields, and in particular to a kind of Litsea cubeba oil extracting method.
Background technology
Litsea cubeba oil (Litsea cubeba oil) refers to the natural perfume essential oil extracted from Litsea pungens fresh fruit, is in
It is yellowish, wherein contain a large amount of citral, have strongly, the lemon of smelling good, between the fragrance of a flower and fruity.Citral
It is the important source material for manufacturing violet copper system row fragrance, for synthesis VitAVitE, vitaminAD agent, is widely used in
In food, medicine, pesticide, cosmetics and other daily necessities.So how high efficiency extraction Litsea cubeba oil just seems extremely important,
Existing extracting method mostly uses the mode of tanning, i.e., Litsea pungens fresh fruit is put into the pot equipped with water and carries out infusion, make the wooden ginger
Seed oil releases under conditions of high temperature from Litsea pungens fresh fruit, since Litsea cubeba oil is incompatible with water, after the completion of infusion
Litsea cubeba oil is separated from water.
But during tanning to Litsea pungens fresh fruit in pot, due in Litsea cubeba oil with carbonyls,
Such as：It based on citral etc., therefore is easily oxidized in air, causes the Litsea cubeba oil extracted to occur rotten, influence wood
The quality of ginger seed oil.
Invention content
The object of the present invention is to provide a kind of Litsea cubeba oil extracting methods, and Litsea pungens is extracted by way of vacuum distillation
Oil, to solve the problems, such as that Litsea cubeba oil occurs oxidation and influences quality in the prior art.
To achieve the above object, the technical solution adopted by the present invention is as follows：
Litsea cubeba oil extracting method, includes the following steps：
(1) it stocks up：Harvesting ripe, intact Litsea pungens fresh fruit clean the impurity on Litsea pungens fresh fruit surface with clear water, and will
The water on Litsea pungens fresh fruit surface drains；
(2) system is dry：Litsea pungens fresh fruit after draining spreads the natural air drying at shady and cool ventilation, and the thickness spread is with the wooden ginger
Non-overlapping is degree between sub- fresh fruit, and is turned to Litsea pungens fresh fruit, and dry Litsea pungens is obtained；
(3) it crushes：Obtained dry Litsea pungens is ground crushing in mill, obtains Litsea pungens powder；
(4) it impregnates：Litsea pungens powder is put into clear water and is impregnated, when immersion is stirred；
(5) it is evaporated under reduced pressure：The mixture of Litsea pungens powder and clear water in step (4) is poured into distillation bucket, air feed is started
Case makes stirring blade be stirred mixture, then starts negative pressure blade and generates negative pressure, then heated to mixture, is made
Ingredient volatilization in Litsea pungens, the substance evaporated will enter condenser pipe in the guiding of negative pressure and condense, after condensation
It flows into recycling bin；
(6) water-oil separating：By in recycling bin Litsea cubeba oil and water be poured into oil water separator and detach, divided
Litsea cubeba oil from after；
(7) dry：Drier is added in the Litsea cubeba oil obtained into step (6), and is stirred, finally with filtering out
Drier obtains dry Litsea cubeba oil.
The principle of the present invention：(1) it stocks up：Harvesting ripe, intact Litsea pungens fresh fruit, removal is rotten, breakage, to obtain
Good raw material；The impurity on Litsea pungens fresh fruit surface is cleaned with clear water, impurity includes dust, pesticide residue etc., obtain it is clean,
The Litsea pungens fresh fruit of safety is standby；And drain the water on Litsea pungens fresh fruit surface, it is dry to shorten follow-up system for the most of external water of removal
The time of step.
(2) system is dry：The moisture in Litsea pungens fresh fruit is removed by natural air drying, obtains dry Litsea pungens, increases oil yield, together
When reduce weight, reduce the burden of following process；Litsea pungens is set to keep flat without being overlapped, and intermittently to the wooden ginger when spreading simultaneously
Son is turned, i.e., carries out turn-over to Litsea pungens, make each face of Litsea pungens that can air-dry uniformly, avoid being packed together appearance
It generates heat and Litsea pungens is caused to rot.
(3) it crushes：Dry Litsea pungens is ground into Litsea pungens powder, it is possible to increase the surface area of Litsea pungens promotes follow-up add
The efficiency of work.
(4) it impregnates：So that Litsea pungens powder is mixed with clear water, using clear water as carrier, forms solidliquid mixture, stirring makes mixing more
Add uniformly, convenient for distilling below.
(5) it is evaporated under reduced pressure：230 degree of the boils up till of Litsea cubeba oil, after direct air-distillation makes Litsea cubeba oil boiling volatilization
Reflux, requires heat to 230 degree, and the requirement to heating equipment and distillation bucket is excessively high, therefore using vacuum distillation, reduces Litsea pungens
The boiling point of oil, reduces the temperature of heating；In distillation process by for bellows air feed be used as drive force stirring, make mixture by
It is hot uniform, it prevents solid-liquid uneven heating even and causes bumping；It is rotated simultaneously by negative pressure blade and generates negative pressure, play decompression and led
The effect of stream, while the air in distillation system is removed, it avoids Litsea cubeba oil from aoxidizing, ensures the quality of Litsea cubeba oil；It is logical
It crosses condenser pipe and condensation and water conservancy diversion is carried out to the ingredient volatilized in distillation bucket, enable its flow into recycling bin and recycle.
(6) water-oil separating：It, at this time can be by oil water separator to the wood in recycling bin since Litsea cubeba oil is incompatible with water
Ginger seed oil is detached with water, tentatively obtains Litsea cubeba oil；
(7) dry：Litsea cubeba oil is further dried by drier, the water that may wherein contain is removed, obtains drying
Litsea cubeba oil, realize purification.
Beneficial effects of the present invention：Compared with prior art,
1, by the way that procedure for preparation is arranged, Litsea pungens fresh fruit best in quality is selected, the matter of Litsea cubeba oil is improved from raw material
Amount；By making the processes such as dry, crushing and immersion, the moisture in Litsea pungens is removed, improves oil yield, while mitigating whole
Weight reduces the burden of following process.
2, it by vacuum distillation, generates negative pressure using negative pressure blade and achievees the effect that decompression, on the one hand remove distillation system
In air, avoid Litsea cubeba oil from aoxidizing, ensure the quality of Litsea cubeba oil, on the other hand reduce the temperature of distillation heating,
The volatilization for accelerating Litsea cubeba oil improves the efficiency of extraction, while can reduce the requirement to using equipment, is thrown to reduce
The cost entered；Setting provides wind regime for bellows, using for bellows, not only drive force is used as to stir, but can carry out heating and
Condensation, can be realized it is not necessary that multiple energy sources are arranged, to using the structure of equipment to be simplified, reduces energy consumption.
3, by the way that drying process is arranged, Litsea cubeba oil is dried after water-oil separating, further removes water, reaches drying
The effect of purification, to improve the quality of Litsea cubeba oil.
Further, it is 20-26 degree that control, which spreads temperature, in the step (2), is turned every 8-12 hours primary.It spreads
Temperature is unsuitable excessively high, prevents the ingredient that part is volatile in Litsea pungens from volatilizing；Turn too frequently can guarantee wood under this condition
The normal of Jiang Zi fresh fruits air-dries.
Further, the granular size of the Litsea pungens powder in the step (3) is 1mm-2mm.Through studying the granular size model
The Litsea pungens powder oil yield highest enclosed.
Further, the time that control is impregnated in the step (4) is 1-2 hours.Keep Litsea pungens powder fully mixed with water
It closes.
Further, the drier in the step (6) is anhydrous sodium sulfate.Anhydrous sodium sulfate has preferable water imbibition,
It is cheap simultaneously.
Further, it is filtered using funnel in the step (6).It is filtered using funnel, it is easy to operate, quick.
